Nearly half of the world's saltwater desalination capacity comes from thermal distillation plants, whether by a Multi-Effect Distillation (MED), Multi-Stage Flash (MSF), or Thermal Vapor Compression (TVC). A desalination plant is essentially a massive train of condensers, where the  cost of the heat exchangers exceeds 1/3 of the total capital cost. DropWise coatings provide an opportunity to shrink the size of the condensing surfaces by more than 30%, delivering substantial savings in the cost of fresh water.
